Hi All,I have a t-rex 600e dfc pro with a ar7200bx.I put a 4 blade rotor head on it .The problem is at zero pitch everything is level
until i give it full pitch or full negative pitch the back servo dose not go up or down enough and tilts the swashplate forward or backward.
any help

Assuming if you have the connections correct
* Menu H (swashplate mixer at 120 - solid red)
* Menu I (swashplate servo direction)
- Use rudder to toggle through settings to see which one will work
- Move the collective to verify the directions

Now that I have re-read your issue, looks like u are getting full travel/deflection from you servo when you are at full negative or positive pitch.
